In case you’re unfamiliar, Bluetooth is a wireless technology that works in close-range proximity.Īnd “close-range” is the keyword here cause one of the most common Dexcom errors is signal loss due to long-range connectivity.Ī Dexcom G7 or G6, or any other Bluetooth device, can only stay connected up to a certain range and withstand many objects before losing the signal. Unfortunately, many users have problems with the sensor only lasting a week vs the advertised 10 days before it starts losing connection, giving wrong or inconsistent readings, or malfunctioning.Īs a reminder, Dexcom uses Bluetooth to connect with your device. 3: Signal strength and connectivity issues There is always a chance that it’s a technical defect. If nothing works, call 1-84 (Dexcom’s tech support) and see if they can do anything about it.

You generally can’t get too far away from your smartphone, smartwatch, or any other device that connects to the Dexcom without losing the signal. See, Bluetooth isn’t the best when it comes to range. More often than not, this happens due to either long distances or objects that block the signal. If you don’t get anything for at least 20 minutes, there is a good chance of something wrong with the setup or a technical issue. Not getting any readings for quite some time is one of the most common Dexcom errors. If it comes down to that, all you can do is contact tech support. Last but not least, there’s always a small chance that you either got a defective unit or that it got damaged somewhere along the way. In this case, all you can do is re-install it and ensure everything was set up correctly. It can also happen due to a bad fit, calibration, insertion, or a wrong setup. Working out or dehydration can also temporarily affect your glucose levels – mainly when the Dexcom is too close to an area where more glucose is burned. But, ask a professional if you can – to be safe. In that sense, it’s not even a false alarm. So, pay attention to when the false alarm comes up and when you’re taking your meds. Certain meds can mess with intestinal fluids and create both false lows and false highs.
